Conveniently, spring means is provided for holding the fingers in adjusted position, the fingers being thus yieldable in the driving operation to permit the staple and the driver to pass. Although the invention is herein illustrated as arranged to insert fastenings in such a manner that the fastenings do not entirely penetrate the work, it is to be understood that the ends of the fastenings could, if desired, pass entirely through the work.

The invention is herein illustrated as applied to a lasting machine of the type disclosed in Letters Patent No. 1,796,451, granted March 1'7, 1931, on an application of George Goddu, and therefore only such features of the general organization as it is necessary to refer to for an understanding of the invention will be mentioned in detail and these features will be referred to only in brief terms.

To assist the operator in determining the proper relation of the shoe to the lasting instrumentalities of the machine there is provided a guide member or shoe rest 38 which is adapted to engage the outer or bottom face of an insole and the inside face of a lip or rib on the insole. The shoe rest 3% is mounted at the front of the machine and may be yieldingly mounted if so desired. The upper is pulled heightwise of the last, as shown in Fig. 15, and then inwardly over the margin or feather of the insole, as shown in Fig. 16 by a gripper comprising a pair of cooperating jaws 32. An overlaying or pressing member 34 (Fig. 2) comprising a staple-guiding nozzle is moved in a direction inclined toward the bottom face of the insole to lay the margin of the upper over the feather of the insole and against the lip and while the upper is thus held clamped against the lip a staple is driven by a driver 36 to fasten the upper to the lip at a point adjacent to the body portion of the insole, the legs of the staple being deflected by the work, as hereinafter more particularly described, in curved paths such as to anchor them in the insole without penetrating the inner face of the lip or the face of the insole in engagement with the last.

In order to provide ample room for manipulation of the shoe and for the operation of the gripper the staple-forming mechanism (which will hereinafter be described in detail) is so constructed and arranged as to form a staple in a location out of alinement with the staple driver 36 and above the path of movement of the driver. The machine is provided with means for transferring the staple downwardly into alinement with the driver between staple-forming and driving operations. For forming the staple there is provided an inside former 33 (Fig. 2) supported on a stationary bracket at secured to the head of the machine by a cap screw 42. The rest of the staple-forming mechanism and the means for transferring the staple from forming position to driving position, with the exception of the wirecutting means, are carried by a slide 44 to which the staple-guiding nozzle 34 is secured by a stud 16 and nut 41', this slide being mounted for reciprocating movement in an inclined guideway in the head of the machine. The slide is moved along its guideway through connections to a cam as clearly shown and described in the Letters Patent above referred to.

Secured to the bracket 49 in fixed relation to the inside former 38 is a wire-guiding nozzle 48 (Figs. 2 and 3) to which wire is fed by means hereinafter described, the wire being advanced until its free end engages an abutment or stop 50 secured by a screw 52 to a member 54 pivotally mounted at 5% (Fig. 8) on a bracket 58 secured to the head of the machine. The member ii l is provided with a laterally extending arm 60 to which there is connected a spring 62 which acts yieldingly to hold the abutment 50 in engagement with a member 64 (hereinafter more particularly referred to). The wire is fed forwardly over a guiding member 66 (Figs. 2, 5, and 6) supported on the forward end of the movable slide 44 which, as hereinbefore stated, carries the member 34 for, laying the upper inwardly over the insole and for guiding the staple as it is driven. The guiding member 66 is provided with upwardly extending portions 68, it! which are provided with rearwardly extending slots which receive the wire and which position the wire in proper relation to wirebending and cutting means. The position of the slots in the upstanding portions 68, 10 relatively to the bending and cutting or severing means determines the length of wire which is to be severed, the wire-feeding means being correspondingly adjusted through. connections which will later be described. The member 66 slides in a guideway formed in an upward extension '52 of the nozzle 34 (Fig. 2) and is provided with a pin 14 to which is connected mechanism for maintaining the member 6% in adjusted position as will also later be fully described. The upwardly extending portions 68, it are spaced apart to receive the inside former and are shaped to prevent interference with stationary parts of the wire-cutting and staple-forming mechanism.

lvliounted on the stationary bracket 40 in front of the wire coming from the nozzle 48 is a wirecutting knife 35 which is provided with a cutting edge i8 (Fig. 6) inclined at a substantial angle to the vertical and with a cutting edge 80 which is perpendicular to the wire and which operates when very short staples are to be made. The member 32 cooperates with the knife 16 to sever the wire and to deflect one end while the members and til deflect the other end in a manner which will later be made apparent. The cutting edge E8 is inclined in order that different portions of the edge will be effective depending upon the length of the piece of wire to be severed. As stated above, the length of the wire severed by these cooperating members is dependent upon the position of the slots in the upstanding portions 68, ll) of the member relatively to the cutting edges 18, 80 of the knife "it and to portions of the stop or abutment it being necessary that the wire-feeding mechanism be properly adjusted to feed the proper length of wire. To this end connections between the member (56 and the wire-feeding mechanism are provided as will be later described.

The members 64 and 82, above referred to, are mounted on the upward extension I2 of the nozzle rearwardly of the member 66 and prior to the wire-severing operation are located just rearwardly of the stationary cutting knife 16, as best shown in Fig. 11. The member 82 is provided with projections 84, 38 (Fig. 3) which cooperate with the cutting edges 18, 8(), respectively, of the knife 56 to sever a length of wire which subsequently is formed into a staple. The projections 84, 88 are beveled (Figs. 3, 11 and 12) so that the wire is first bent and then cut as it is forced against either the cutting edge 18 or the cutting edge 80 of the knife 16. Thus a deflected point or end is formed on that end of the severed length of wire.

The abutment or stop 53 is provided with a stepped or serrated portion 99 (Figs. 3 and 8) the general inclination of which is substantially the same as the cutting edge 18 of the wire cutter 16 but in the opposite direction. The abutment B is also provided with a substantially vertical portion 92. The end of the wire is fed through the slots in the upstanding portions 63, ID of the guiding member 66 and against either the stepped portion at or the vertical portion 92 of the abutment as. The member 64 is provided with a projection having an inclined portion 94 and a vertical portion Q6. The member 54 is located forwardly of the stepped portion 99 and the vertical portion 92 of the abutment 50 and has an upper face which is inclined in the same direction as and is flush with the top of the stepped portion 90, and also a shoulder 98 (Figs. 11 and 12) extending laterally of the vertical portion 92. When the member 64 moves forwardly the end of the wire is therefore caught between the member 54 and either the portion 94 or the portion 96 of the member 64 which portions are beveled so that the end of the wire is bent toward the same side of the wire as the bent or deflected point of the other end of the severed length of wire. As the end of the wire is bent or deflected the member 54 yields more or less lengthwise of the wire against the resistance of the spring 62 (Fig. 12) in response to pressure of the wire against it to permit the end of the wire to pass. This operation takes place at the same time that the other end of the length of wire from which the staple is to be formed is bent. Fig. 12 clearly illustrates the positions of the various parts of the wire-cutting and deflecting mechanism at the conclusion of the bending and severing operations.

In the operation of the wire cutting and defiecting or bending mechanism. the wire is accordingly fed through the wire guiding nozzle 48, through the slots in the upstanding portions 68, 15 of the wire guiding member 56 and against the abutment at. The slide rid which carries the cutting and deflecting members 82 and 54 then moves in a direction toward the operator to bend the wire as above described and then cuts a piece of wire from the length of wire adjacent to the bend made in the wire by the members 32, It. Further movement of the slide 4? causes an outside former lilil carried thereby to engage the piece of wire and bend or shape it about the inside former 38. A staple W2 is thus formed with the ends of the staple legs deflected outwardly away from each other in the general plane of the staple (Fig. 13), and because the outwardly deflected ends are engaged by the sides of the outside former in the forward movement of the latter, the staple legs as a whole are bent far enough to converge toward their ends. The staple IE2 at this time is in a position to be transferred to the driver passage in the nozzle 3d, and it is thus transferred by downward movement of the outside former IUE! in the manner described in Letters Patent No. 1,796,- 451 hereinbefore referred to.

At the same time that the staple I02 is being formed the nozzle 34, secured to the slide 44, is being moved toward the shoe which is being lasted, the upper U of the shoe having been gripped and pulled by the lasting pincers 32. The lasting pincers are first given an upward movement to tension the upper (Fig. 15) and are then moved inwardly (Fig. 16) to draw the upper over the insole S, whereupon the nozzle 34 engages the upper to lay the upper over the margin of the insole. It is to be noted that the nozzle 34 presses the upper closely into the angle between the lipRof the insole and the feather or margin of the insole, and guides the staple I02 in such a path that it is driven very close to the base of the lip R. During these operations the shoe rest 36 engages the bottom face of the insole and the inner face of the lip R. close to the base of the lip, thereby resisting the pull of the pincers 32 and acting as a gage for the work. The operation of the lasting pincers 32 and the staple-inserting instrumentalities described just above is substantially the same as in the Letters Patent above-mentioned, to which reference may be had for a more detailed description of the construction and operation of these parts.

The staple i 02 is transferred from the position in which it was formed to the driver passage at the end of the movement of the nozzle 34 and prior to the operation of the driver. The mechanism contained within the nozzle 34 for determining the depth to which the staple m2 is to be driven into the work will now be described. The nozzle 34 is provided with a driver passage 59-; which receives the staple E62 and acts as a guide for the driver 36. As best shown in Figs. 7 and 10, which are bottom views of the nozzle with the cover removed, a pair of fingers me, m8 located in recesses in the bottom of the nozzle 34 extend into the driver passage NM. The forward ends of the fingers its, Hi8 are urged toward each other by springs H5, H2 which bear against the nozzle 36 at opposite sides thereof and against the rear ends of the fingers. As illustrated, the fingers E66, E08 are pivoted to the nozzle 34 at H4 and H6, respectively. The forward ends of the fingers are spaced apart by a block i it which is located between the fingers E33, N33 and above the driver passage in the nozzle 35. This block is arranged to be moved toward and away from the end of the nozzle, thereby varying the distance between the ends of the fingers. The block M8 is secured to one end of a sliding bar lit which is connected at its other end to an eccentric on a shaft E22 provided at its outer end with a handle i 2 by means of which the shaft lEZ may be turned to move the block H8 toward or away from the end of the nozzle 34. The fingers W3, I58 by engagement With the ends of the staple legs act to bend or deflect them farther toward each other to determine the distance between the ends of the legs of the staple at the time when they enter the work, It will be understood that in the driving operation the fingers H28, H58 yield to permit the wider portion of the staple and the driver to pass.

As above stated, the deflection of the legs of the staple I532 by the fingers Hit, 68% determines the depth to which the staple is to be driven. For example, if the stock into which the staple is to be driven be relatively thin the legs of the staple will be deflected toward each other only a very small distance, but if the staple is to be driven into relatively thick stock the legs will be deflected toward each other to a substantially greater degree. This is because of the fact that nearer the bent or deflected ends of the legs of the staple are brought together the greater will be the angle between the deflected ends of the staple and the surface of the work into which they are to be driven and, accordingly, the deepor the staple will be driven into the stock and, conversely, the greater the distance between the bent or deflected ends of the staple the less distance the staple will penetrate into the work. It is desirable that the fingers 558 be adjusted to deflect the legs of the staple so that the ends of the legs will not penetrate the entire thickness of the work. As shown most clearly in Fig. 20, the ends of the staple legs are deflected by the Work in such directions that the staple legs are turned outwardly away from each other and away from the crossbar of the staple and follow curved paths in the work located substantially in the general plane of the staple.

When the nozzle completes its movement toward the shoe to force the marginal portion of the upper closely into the angle formed by the feather of the insole and the rib shown in Fig. 17, the driver 3% is thrust forwar ly under the influence of a spring to drive the staple into the work. The ends of the staple legs strike the work at an angle and are deflected outwardly, as above described. The lasting pincers 32 in the meantime released the upper and have returned to their original position. The nozzle or overlaying member is then retracted and the parts of the machine are in position to begin another cycle of operations.

Although the invention is illustrated as embodied in a machine particularly adapted to attach uppers to a lip or projection on an insole, it is apparent that the machine may well be used to secure uppers to insoles of other types of shoes where it is desirable that the fastening should not penetrate through the work. Referring now to Figs. 14 to 18, inclusive, it will be noted that the staple M32 is driven into the lip or projection on the insole very close to the base of the lip and, in fact, the staple is anchored in the lip adjacent to the body of the insole without penetrating through the lip. The staples being thus driven into the lip or projection adjacent to the body of the insole act to hold the overlaid margin of the upper flat upon the feather of the insole without substantially any relaxing of the lasting strain or distortion of the lip or projection of the insole after the lasting instrumentalities have been removed. The desired angle between the overlaid margin of the upper and the lip of the insole is thus maintained, thereby insuring the best results from the succeeding operations upon the shoe. In operating upon shoes having shouldered insoles of the type. shown in Fig. 19, the staple N32 is anchored in the body portion of the insole without penetrating through the insole, as shown in Fig. 20. Among the advantages as applied to this type of shoe the channel flap will lie close against the insole and produce a smooth bottom by reason of the absence of any portion or portions of the staples in the inside channel of the insole. Substantially the advantages apply to the manufacture of turn shoes where the shoe is lasted with the upper wrong side out and then after being stitched is turned right side out. The channeled surface of the sole then becomes the inside tread surface which is relatively smooth because of the absence of staples in the channel.

The machine is provided with mechanism for feeding wire I25 to the wire-cutting and stapleforming mechanism. A reel E28 (Fig. l) for carrying a coil of wire is supported on a bracket 536 secured to the head of the machine. The wire G25 is fed over an idler roll E32 and over a toothed feed roll I35, the wire being held against the toothed feed roll I34 by a roll E36 which is spring urged toward the roll 5 34. From the feed rolls the wire is fed through a tube 538 to the wire guiding nozzle 48. The feed roll l34 is operated by a pawl and ratchet mechanism through a link Mil and a bell crank lever M2 provided with a roll Md engaged by a cam MB. In order to stop the feed of the wire, if desired, there is provided a finger which may be turned by a handle l52 into position to engage a face I54 on the lever I42 and thus to hold this lever in such a position as to prevent it from being operated by the cam M8. The operation of the wire-feeding mechanism thus far described is the same as in the Letters Patent above referred to.

In order to control the length of feed of the wire in accordance with the desired length of the staples, the machine is provided with mechanism which Will now be described. As previously stated, the length of the staples is dependent upon the location of the slots in the upstanding portions 68, ID of the member 66 relatively to the inclined portions 18, 90 of the wirecutting and deflecting mechanism. The member 56 is provided with the previously mentioned pin M which is connected to one end of an extensible link I56 (Figs. 2 and 4) through a disk I58 provided with a slot I60 into which the pin extends. The disk I58 is fast on one end of a shaft M32 which is mounted in a bearing formed in a block I64 secured to the nozzle 34. The other end of the shaft I62 is secured to one end of the link I56. The other end of the link I56 has pivoted thereto a block I66 which is slidably mounted in a guideway IB'I formed in a member I68 (Figs, 1 and 4). The member .38 is mounted to slide vertically in a guideway formed in the head of the machine, a plate I'IU secured to the head of the machine being provided for holding the member I68 in the guideway. The slidable member I68 is provided with a vertically disposed series of holes in any one of which a pin H2 may be placed. The pin I12 by engagement with the plate at the upper end of a slot I'M in the plate or by engagement with an adjustable screw I15 threaded into the lower end of the plate limits movement of the member I68 in either direction. Themember I58 is connected to one arm of a bell crank lever H6, pivoted to the head of the machine at I18 by means of a pin and slot connection Hill, I82, the lever I16 being provided with a second arm I84 by means of which it may be swung about its pivot to move the member 68 in its guideway between the limits determined by the engagement of the pin H2 with the plate I'Iil or the screw M5, the friction between the parts holding them in the positions into which they are moved by the bell crank lever I16. This movement of the member I68 acts through the link I55 to rotate the shaft H52 and the disk I58. Rotation of the disk I58 acts through the pin and slot connection M, I60 to raise or lower the wire-guiding member 66. In addition to controlling the heightwise position of the member t movement of the bell crank lever I'lB controls the length of feed of the wire. The member I68 is connected to a bell crank lever I85 (Fig. 1) by a pin I88 which fits into a slot I91 formed in one arm of the bell crank lever. The other arm of the bell crank lever I 83 is provided with a cam surface I92 which engages a cam roll I94 mounted on one arm of the bell crank lever M2. The cam surface I92 is so formed that as swinging move ment in a counterclockwise direction (Fig. 1) is imparted to the bell crank lever I86 by upward movement of the member I68 a swinging movement in a clockwise direction will be imparted to the bell crank lever I42 against the resistance of a spring (not shown) to move the cam roll I44 away from the cam I46. In other words, the position of the bell crank E86 determines the amount of lost motion between the cam roll 5M and the cam I46, thus determining the length of feed of the wire. It should be noted that through the connections above described the length of feed of the wire and the position of the slots in the upstanding portions I58, it! of the guiding member 65 relatively to the cutting instrumentalities are adjusted at the same time through movement of the bell crank lever H6. This affords a quick adjustment to vary the lengths of the staples as may be desirable, for example, in lasting with longer staples in the shank portion of the shoe than along the fore part. It will be evident also that if the pin H2 is shifted into a diiferent hole in the member I68 the two staples produced will be either longer or shorter as a result of such shifting.

It will be evident that, as the upper is pulled inwardly over the insole by the gripper 32 and is additionally forced inwardly by the overlaying or pressing member 34, considerable force is applied to the shoe, tending to displace it laterally or in a direction transverse to its height. The shoe is normally held against displacement by engagement of the shoe rest 30 with the lip of the insole and in part also by such friction as there is between the insole and the lower end face of the shoe rest due to the upward pressure of the shoe against the shoe rest as the operator holds and supports the shoe. In order to insure against any possible danger under some conditions of distortion of the insole lip by too great a strain thereon or of such displacement of the shoe relatively to the shoe rest 30 as to result in the driving of a staple or staples in improper relation to the lip, as well as to relieve the operator of the necessity of exercising any special care in holding the shoe in such manner as to guard against these results, the machine herein shown is provided with a member I96 which is moved intermittently into and out of engagement with the insole at a location near the shoe rest 30 and has sharp prongs to penetrate the insole, as fully disclosed in the previously mentioned application of which this application is a division.

In the use of the machine on a shoe having a lipped insole the operator presents the shoe with the lip of the insole in engagement with the work rest 30, starting preferably at the forepart of the shoe adjacent to the previously pulled over toe portion of the upper, and then treadles the machine and holds the treadle depressed while moving the shoe lengthwise, thus lasting the shoe progressively from the toe end to the heel end. If the shoe is one having a shouldered insole, or if it is a turn shoe having a shouldered sole, the shoe is presented with the member 30 in the inside channel of such an insole or sole. In each cycle of operations the grippers are first moved downwardly and outwardly from the position shown in Fig. 14 to grip the upper; then upwardly and outwardly to tension the upper and then inwardly over the feather or margin of the insole. During the cycle of operations a staple is formed and transferred into the driver passage in the nozzle or overlaying member 34 by mechanism previously described. The overlaying member 34 is moved forwardly from the position shown in Fig. 14 to the position shown in Fig. 17 to lay the upper against the lip and the margin or feather of the insole. When the overlaying member is in the position shown in Fig. 17, the staple in the driver passage is driven into the work close to the base of the lip R. and as the staple is driven its legs are deflected by the work in opposite directions to anchor them in the lip without penetrating entirely through the lip, as hereinbefore described. If the staple is driven into a shoulder of the sole or insole (Fig. 19) its legs are anchored in the body of the sole or insole by the deflection thereof in opposite directions without entering the inside channel. The parts of the machine are thereafter returned to starting positions ready to begin another cycle of operations upon the shoe.

The novel method of lasting herein disclosed and the product of the method are claimed in another divisonal application Serial No. 742,334, filed August 31, 1934.
